llsiran STATES ATENT P THEODORE A. PALM, OF \VHITE HOUSE, PENNSYLVANIA.

WHEEL-CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 252,794, dated. January 24, 1882.

Application filed August 26, 1881.

To all whom it may concern Be it known that I, THEODORE A. PALM, of White House, in the county of Cumberland and State of Pennsylvania, have invented certain Improvements in WheelOultivators, of which the following is a specification.

This invention relates to certain improvements in wheel-cultivators,which will be hereinafter described, and set forth in the claims.

Figure 1 is a plan view of the cultivator containing the improvements. Fig. 2 is an end view of the same in the rear. Figs. 3, 4., 5, 6 are details of the several parts. Fig. 7 is a sectional view of the wheel-spindles and the axle-tree stock with the wheel removed. Fig. 8 -is a side view of the cultivator in part, showing the connecting-bars whichsustain the back rod for moving the wheels.

A is an axle tree stock, to which is attachet the shaft or pole, which in this case is bifurcated to give stiffness to the whole frame. A A are bent axle trees or spindles, which are bolted to the under side of the axle-tree stock A at each end, and on which axle-trees A A are supported wheels A A B B, &c., are plow-points or shovels, which are supported by bolts on U-shaped bracketpieces b l), &c., Fig.3, which at their upperends are bent over like a hook, and in the curved part having a hole, I), through which is arod, c, passing through the plow-point standard 0 and through springs 0. These bracket-pieces b b are pivoted within other bracket-pieces, G U, which are U-shaped and bolted fast to the standards 0 (J. It will be seen that by this arrangement of the plow-points B B they are able to spring to a certain extent and yield as they encounter the inequalties of the ground and avoid being broken, as is often the case otherwise.

I) is a rod of metal, which extends across the machine in the rear of and parallel to the axle-tree stock A, and which connects two bars, D I), that are pivoted at the ends of the stock A on two upright rods, to a, which are fastened to and sustained by the bent axles or spindles A A, and in plates a a, which are bolted to the ends of A. a is a brace-rod, which is socketed on one of the bars D, and is hooked into the frame I (Model) I at 1' whenever it is desired to keep the frame in its stationary position, or in moving to orfrom the field, as shown in solid lines, Fig. 1. When used in plowing this rod a is to be removed to permit the wheels to be turned, as seen in broken lines in Fig. l.

D D are curved yokes, which are attacln-d to the rod 1), and which are designed for the feet while the driver is seated. When he is walking behind the cultivator he moves the frame with his hand by the handle H, which is attached to one of the yokes D and pivoted to the stock A, but when riding the handle can be removed.

Fig. 3 represents the manner of constructing and the frame by which the beam is elevated or depressed to lift the plow-points out of the ground or let them down for work to any depth.

G is the beam, 0 O the standards, and B B the plow-points, as before described.

E E are grooved straps attached to the side of the beams, having the slots 6 c therein and bolts to fasten the straps E E, and yet allow them to slide to the extent of the slots, so that either beam can rise and fall over any obstacle, when encountered, independently of the other. These straps E E unite attop and are bolted to the end of a bell-crank handle, E, which is pivoted to the middle of the axle-tree. stock A. This handle E has on one side a pin, it, and there is a spring-catch K which holds the bandle by the pin it when in the position shown in dotted lines in Fig. 3, when the beam G will be held up, as also seen in dotted lines, and with it the plow-points, which will then be out ofthegronnd and some distance above it. (Not shown in Fig. 3.) The plow-beams have a bifurcated strap, g,which is pivoted to the. under side of the cross-beam Lon rods F F suspended beneath L, as seen in Fig. 6, fiom adjustable brackets l l, which can be made to move to right or leftwithin acertaincompass by means of slots-in them, and set-screws for the purpose of shifting the shovels or plow-points to or from the rows. The straps g g are the clevises, which can be adjusted to run the plow-points deep or shallow by shifting the bolt-holes in the end of the beams G.

M is the drivers seat on the frame I, which frame and seat are so constructed as to be readily removed. When the driver is to walk side boards, N, are attached to the shovels.

The spindles or bent axles A A are attached to the rod D by means of brace-rods D D immediately under the bars D D which rods D are rigidly attached at the other end to the upright rods a a beneath the spindles A, so that, the rod D beingthus attached at each end to the spindles A A by the braces D and the bars D D, which latter are pivoted to the upright rods (0 66. whenever the rod D is moved to the right or left the spiiidles A A are correspondingly moved and carry the wheels also, as represented in Fi 1 in dotted lines, thus causing a divergence in the direction ot' the cultivator.

l) D are braces extending from the spindles to the cross-beam L, which serve the purpose of bracing the frame and giving steadiness to the axle-tree.

- Beneath the axle-tree stock A is the whittletree-bar O, which is pivoted in the middle to the stock A by the pin 0. From this bar 0 are two rods, 0 0, which pass through upright plates 0 0 on the cross-beam L, and which have their outerends formed into hooks upon which are hung the whifiietrees.

I -claim 1. In a wheel-cultivator, the combination, with the cross-beam A, having hinges or cars, of the swiveled wheel parts a, the upper and lower brace-bars, D D the cross-bar D, ha"- ing foot rests D and the leverH, substantially as and for the purpose described.

2. The combination of the drag-bars Gr,with bii'urcated straps g, and adjustable brackets F l, with the slotted yoke-bars E, elbow-lever E, and hook K, substantially as and for the purpose described.

3. The shovel-blades B, having central ears, I), hinged to the standard-brackets, in combi nation with standards 0, tension-rods c, and springs c, substantially as and for the purpose described.
